STERILIZING DEVICE.

Specification of Letters Patent.

' Application filed July 5, 1910. Serial No. 570,250. I

To all whom it may concern.

Be it known that I,,HENRY W. PATRICK, a citizen of the United States, residing at Elyria, county of Lorain, and State of Ohio, have invented certain new and useful In 1- grovements in sterilizing Devices; and I 0 hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same; My invention relates to devices for sterilizing drinking cups or the like and is more part cularly adapted for use at public drinkmg places, where it is desirable to sterilize each cup before it is used. I aim to produce a device, which will accomplish this with as little trouble to the drinker as possible.

My invention will be best understood by reference to the followin' description when taken in connection wit the accompan ing illustration showing one specific einbo inient thereof, while its scope will be more particularly pointed out in the appended claims.

Figure l is a front elevation, partly sectional, of my device. Fig. 2 is-a vertical section. Figs. 3 and 4 are detailed views.

Referring now to the drawing and the embodiment of my invention there shown, I have illustrated at 1, a casing. A chamber 2, is shown in the upper part of this casing. Sprocket wheels 3 and 4 are shown pivoted to the casing. A sprocket chain 5 is connected to these wheels and is adapted to move thereover. This chain serves as a conveyer for cups 6, which are removably attached thereto by the spring clips 31. To one of the sprocket wheels, I attach a. small crank, 17, which projects outside the front of the casing to rotate the sprocket wheel 4,

and is adapted to be operated by the drinker to move a cup to a position where it is accessible to him. A liquid duct 7, leads into the casing from an outside reservoir.

At 8 I show a steam boiler, which is con-' nected by pipe 9 to theduct 7. A valve 10 controls the fiow of water from the pipe into the boiler. I admit water through this pi e to the boiler to be converted into steam f dr Mounte sterilizing purposes. The pipe 7 is expanded at 7 and a valve 11, pivoted in this expanded portion. A spring X is connected through a lever. 18 to the valve 11 tending to ho d it in closed position. When the Patented Nov. 1, 1910. h

valve 15 is opened, the water flowing in the pipe overcomes the pressure of this s ring opening the valve. When 15 is close the valve encounters the static pressure alone,

and the force of. the spring is sufiicient to close the same. At 12 I show a second pipe leading from the duct 7 into a valve box 21. The duct 7 is continued at 13 to a spigot 14. The fiow of li uid through this spigot is controlled byt e hand operated valve 15. A spring pressed lever 18, connects the valve 11 toa rod 19. On one end of this rod is a piston valve 20, which works in the valve ox 21. At 18I show a device for admittin cold water to cool the sterilized cup. This device is connected by a duct 19 to the valve box 21. On the other end of the rod 19, I show a similar valve which works in a' valve box 23. The valve box 23 is coni a duct 30, to the steam boiler 8. upon the top of the box .23, is a funnel shaped device 24 adapted to conduct the steam from the valve box to the cup to be sterilized.

25 is a safety valve for the boiler. At 26 I show means for converting the water in the boiler into steam. In the form shown, I show a gas pipe and burner. 27 is a duct for conveying away the waste water which is cast thereinto through an opening 28 in the frame. The frame 1, has a recess nected lay at 32 in which a pin 33, on the crank'17 catches. 'This pin is spring pressed to enter this recess by spring 34. I

At 16 I show openings in the chamber 2,.

through which the cups are carried by'the conveyer. 15 to draw water into the cup 6. The flow The drinker operates the valve I of water through the duct 7 and 13 opens r the valve 11, which operating through the lever 18, and the rod 19, moves the piston heads 21 and 22 to the left hand positions opening the valve in theboxes 21 and 23,

so' that steam passes from the boiler '8 I through the pipe 30 and a funnel 24 into the cup 6. Cold water passes from the pipe 13 through 12, 19 and 18' to a second cup which has previously been sterilized to cool the'same. When the drinker has finished, the cup is placed upon the conveyer and the crank 17 rotated moving it to the next osition and moving the next cap, which as been sterilized to the position in front ofthe spigot. The drinker may perform the operation ofchanging the position of the on )s before he drinks ii desired.

hile I have shown this particular form and have described this particular mode of operation, it will be obvious to those skilled in the art, that numerous and extensive departures from the forms and details of the apparatus here shown, may be made without departin from the spirit of this invention. The orm shown and the mode of operation described, being here presented solely for the purpose oi illustrating this invention.
